c# - .NET / Oracle: How to execute a script with DDL statements programmatically -


i want programmatical schema manipulation against oracle database in c#. therefore, struggle basic issues.

the ddl sql statements located in script file. not want use sqlplus.exe, want use oraclecommand out of odp.net assemblies (system.oracle.dataaccess). here's example of script file:

script.sql:

drop table abcdef;   drop table ghijkl;

i want point out:

  • the script contains ddl statements (data definition language)
  • the script contains empty lines
  • the script contains more 1 statement

the following code should execute script:

var content = file.readalltext("script.sql");  using (var oracleconnection = new oracleconnection(_connectionstring)) {      oracleconnection.open();       using (var command = new oraclecommand(content) { connection = oracleconnection })      {           command.commandtype = commandtype.text;           command.executenonquery();      } }

executing code, oracle error:

oracle.dataaccess.client.oracleexception: ora-00911: invalid character

maybe there issue formatting of statements, think. hint appreciated. thank you.

---edit---

to summarize needs in simple way: search approach execute sql/ddl script, executable sql plus, programmatically c#.

as @steve said, semicolons causing error. , can't wrap entire file single execute immediate command, since can execute 1 statement @ time. need parse file , execute each command on own, removing semicolon delinates commands. parsing have deal string literals, noted, in addition containing semicolons may contain doubled single quotes ('') within single quotes (') begin , end string literal.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
